TIRE.

1 Specification of Letters Patent.

Patented Mar. 11, 1913.

Application led August 2. 1911. Serial No. 641,907.

To all whom it may concern: vBe itnknown that I, MARTIN L.` KEAGY, a

.citizen of the United States, residing at Canton, county of Stark, and State of Ohio,

may still be maintained in use without in' jury tothe tire or the wheel rim.

A further object of `my invention is to provide a device as mentioned which may be supplied to the trade eitherL-as a complete tire or as a core to take the place of the usual inner tube in a tire of any ordi nary or preferred form.

Other objects will appear hereinafter.

' With these objects in view my invention 'consists generally in a body portion of a tire or core for an outer tube, said body or core being provided with a plurality of circumferential cells each adapted to contain an inatable tube and so constructed that the inner or inflat-able tubesmay be readily inserted or removed andv independently indated. y

My invention further consistsin certain reinforcements for the body or core to prevent collapsing or distortion of the tire should one of the inflatable tubesl be punctured.

-My invention further consists in various details of construction and arrangements of parts all as will be fully described-hereinafter and particularly .pointed out in the claim.

a tire embodying my invention in its preferred form. Fig. 2 is a similar view of a core embodying my invention and adapted 4to be inserted within the outer tube of an ordinary tire, and Fig. 3 is a detail view looking at the inner or rim engaging face and illustrating the position of the in'lating nipples.

Referring now to Figs. 1 and 3 of the drawings, 1 indicates the body of the tire which may be of any desired form but which I have illustrated of the usual shape to be arranged upon 4an ordinary clencher rim. The body 1 is formed generally of alternate layers of friction cloth, such as canvas or duck, and sheets of rubber, 2 and 3 respectivelyvu1canized together. The body 1 is formed with a plurality, preferably three, circumferent-ially extending cells 4, 5 andf6, which are preferably circular in cross se ction, and which are adapted tol receive inflatable tubes/Z The-body is also'formed with circumferential. slots 8, 9 and 10 which extend :to the cells 4, 5 and 6 respectively and through which the tubes4 7 may be inserted or removed. The several slots preff erably converge to a single slot 11 disposed 'centrally of the base 12 of the tire. When the tire is removed from the rim it may l readily opened at the several slots to insert or remove the tube 7 13 indicates the inflat-ing nipples for the several tubes 7 which are preferably arranged near together as illustrated in Fig. 3 to facilitate iniating the tire.

The body 1 is covered with a layer of rubber 14l extending vabout the body from one groove 15 to the other, which grooves receive the edges of the clencher rim. 16 indicates the tread which is formed of rubber, thick at the center and tapering toward the edges and extending substantially half way around the body of the tire, The portions 14 and 16 are vulcanized tothe body 1, or rather the laver 14 is vulcanized to the bod and the tread 16 to the layer 14. Interpose between the layer 14 and tread 16 are preferably interposed several alternate layers of friction cloth 2 and rubber 3 forming a filler 17 which, when the device is vullcanized, causes the tread 16 to more securely adhere to the tire. The filler 17 does notI extend quite to the edges of the tread so that said edges are vulcanized directly to the rubber layer 14. By this construction the fabric is'ent-irely protected from moisture. Should the tube in the outer cell 4 become punctured, the tubes in the inner cells 5 and 6. will prevent collapsing of the tire and injury to the tire or rim. Should either oi the tubes in the inner cells become injured the other tubes-will, in a greatmeasure, support the weight of the vehicle, but tb prevent undue distortion of the tire in such event, I provide the tire-with reinforcing rings 18, 19v and 20 which' are formed of maarre hard or car-spring rubber and embedded in the body 1 between the cells and between the slots and also between the inner cells and the base l2.

ln Fig. 2 I have illustrated my invention embodied in a core adapted to be placed within the outer tube of a tire to take the place of the ordinary inner tube. ltnthis form of my invention the core 1a is formed substantially the same as the body 1 of the tire above described except that it is circular in cross section and the covering 14 vand tread 16 are omitted, as well as the rim engaging base 12, otherwise the construction is the same.

Having described my invention what 1 claim as new and desire to secure by Letters Patent is circumferential cells, two of said cells being arrangedside by side adjacent the base of said body and the third cell being arranged centrally of the body and adiacent the periphery, said body being also provided with slots communicating with said cells, and circumferential rings reinforcing said body and located between the outer cell and the two inner cells, between the inner cells and the base of -the body and between said slots respectively, substantially as described. 1n testimony whereof 1 have signed my name to this specification in the presence of two subscribing witnesses.
